طقم حساس MAP نحاسي 3.5 BAR أو 50 PSIA مع موصل Flying Lead من AEM

AEM 3.5 BAR Brass MAP Sensor Kit

AEM offer high quality brass PSIa sensors in 30(2BAR), 50 (3.5BAR) and 75 (5BAR). PSIa is referenced to absolute zero. Absolute zero is the pressure measurement when all the pressure exerted by the atmosphere has been removed. The most common use for absolute pressure sensors is reading manifold pressure. PSIa sensors are required of you wish to measure vacuum.

A PSIa sensor will read about 14.7 PSI when the sensing element is exposed to atmospheric pressure at sea level however they can be recalibrated to read zero at atmospheric and a negative number at values less than atmospheric pressure.

There are many different tools that can be used for measurement, but the degree of accuracy is dependent upon the tool. For example, a ruler can measure distance with a good degree of accuracy, but for a more precise measurement a caliper should be used.

The difference between a brass pressure sensor and a stainless steel pressure sensor is similar if we think about it in these terms:
